To all whom t may concern:

` Be it-lrnown that TON, a citizen 'of the United States, and a resident of Jeerson, in the county of Soho harie andState of N ew York, have invented certain-new and useful Improvements in De, the following livery Mechanisms, vof which is a specification;

class specied, vsimple in construction and which will operate automatically and deliver the sheets with accuracy andspeed.

`With these ends in view and others which will appear hereinafter, my improvements comprise features which are illustrated in theirprei'erred embodiment in the drawings accompanying this specilicationl wherein igure 1 is a side elevation of the delivery end of a4 drying oven, including a sectional view on line 1-l of Fig. 2 of a por- 'tion of my improvements. Fig, 2 is a front endy elevation, partly in section on line 2-2 of Fig. l, oi what is shown and showing further details of the device. ig'. y3 is a side elevation, looking in the direction of arrow 3 of F ig. 2. All the figures of the drawings are to one scale.

My improvements plied to the delivery of plates such as of tin plates are passed bymeans of endless chain 5 carrying s eleton wings 6. The plates are deposited between said wings 6 respectively, as at 7, by means not shown, troni some source of supply, such as a coating machine not shown. ,The wings tvwiththeir coated faces uppermost, as at 8, as they are carried through by said chain. As lthe plates are advanced y the lower run of the chain toward their place of deliver their lower edges respectively drag along on guideway table 9 on the oven bottom l? just below the aXis of sprocket' 10, each plate encounters one or more toothed wheels as 11 rotating at a surface speed in excess of that of chain 5. Plate 7a has just enn countered said y wheel and plate 7b has `just passed out of engagement therewith. the same time wing 6ad has passed upwardly in its curved path around sprocket 10 therel, MARCUS D. Bonera* clined in said Fig. l. v

, thereon by areJ illustrated as ap-' rom a drying evene, through which said plates lie against -saidY the oven and, as they reach a point moving it when filled with 26 and Patented aprn 19, 119.21., serial nemesio.

by moving out of the path of plate 7b driven forwardly by wheel 11. rlhe function of said'toothed wheels 11 isto lift and advance theplate, thereby freeing it from any adhesion to the wing which has impelled it through the drying oven.

Moving forwardly, 'as indicated by its arrow,. over guideway table 9 are feed chains 12, 12 traveling at about the speed of the outer ends of wings 6 as they pass about sprocket 10. These chains are .supported on sprockets as 13, 14 and may .driven from shaft 15 lof sprocket la, by meansnot shown. Guideway table 9 isuinupwardly at 9a to conform to the path ofl travel of the ends of wings 6 as they pass about sprocket 10 and farther on,

at 9", saiditable is inclined downwardly to permit the plates to slide ed from 'chains 12, 12 onto a series oi' horizontal rolls 16,v

1?, 18, 19, preferably having their axes at right angles to the axes oi sprockets 10, 13 and 14. Said rolls form a roller table for the reception. and advancement of the plates. f

` Rolls 17V, 18 are rotated by belt 20, from means not shown, in clockwise direction, Fig. 2, and rolls 16, 19 may be similarly driven if desired. Said rolls are driven at suiiicient speedto advances plate delivered position ,'76 on .rolls 16, succeeding'plate 7 is rolls. Y

iPivoted to base 21, which supports rolls 16, 17,' 18, is lift-frame 22. i aid. fra-Ine preferably pivoted coaxially with roll 18, comprises two side members 23, 24 having downwardly reachin side wings as 24a which act as side guides to the plates deposited therebetween; which terminate in handlesas 24h, are tied together near their outer ends by front wall 25 which facts .as a'stop and gage plate against which the plates are delivered. Rear wall 26 is pivoted at its upper end to side members 23, 24 of lift-frame 22.

Said front wallv 25 and rear wall 26 rest upon table 27 having legs 28, 28, so that a truck may be run under said table for replates. Liftframe 22 may be provided with counterbalance 29 extending rearwardly from its pivot. Reaching forwardly from back plate pivoted to opposite vertical edges having hooks 33 for 17,*before the next .delivered onto said thereof are arms as 31 chains 12, away from receiving Said side members,

engagement with pins as 34 on the verticall edges of front wall 25 for holding said back plate in place. Said arms as 31 may be connected by front bar 32 if desired. For freeing said hooks from their pins respectively when it is desired to raise the lift-frame, links 35, 36 connecting said arms with levers 37 38 pivoted to the respective side members 23, 24, are provided. Said levers 37, 38 terminate outwardly in handles just under the handles 'respectively of side members Extending between side members 23, 24, between rolls 18, 19 is stop wall 40, efficient when vlift-frame 22 is raised, for preventing any plate from being delivered therebeyond.

The operation of my improved delivery mechanism will be readily understood from the foregoing description and may be briefly set forth as follows: As the plates 7 are advanced by wings 6 of the drier chain plate, 7a encounters toothed wheels 11 by which it is raised and advanced ahead of its impelling wing to position 7b, where the lower edge thereof rests on chains 12 by which it is advanced forwardly and upwardly until it passes over the high portion of the chains as they pass over sprockets 13. The plate then slides through position 7d onto rolls 16, 17 position 7e, where its further movement in that direction is prevented by walll 39 of base 21. From there said rolls advance the plateat right angles to its previous direction of travel onto rolls 18, 19 and thence between lift-frame members 24 and between end walls 25, 26 which with the depending sides as 24* of frame members 23, 24, forni a receiving box for the plates. When this box is suiiic-iently filled the handlesl of levers 37, 38 are lifted into contact with the handles of side members 23, 24, thereby unlatch'ng the hooks, as 33, from their respective pins whereby back wall 26 is free. Then xboth sets of handles are lifted together to the dotted position of Fig. 2 whereby the pile for removal with table 27. While said frame is in lifted position any plate advanced by rolls 16, 17, 18 will be prevented from being delivered by stop wall 40.
